 ## Notes
 
-- The production Dockerfile clones the latest version from the GitHub repository
-- The local Dockerfile uses the current source files for development
+- **Main Dockerfile**: Uses local source files for maximum reliability
+- **Dockerfile.production**: Attempts to clone from GitHub but may fail in restricted environments
+- **Dockerfile.local**: Same as main Dockerfile but with explicit naming for development
 - The application runs on port 5000 inside the container
 - Environment is set to Production by default in Docker containers
 
 ## Troubleshooting
 
-If you encounter SSL certificate issues during build, you can:
+### Git Clone Authentication Issues
 
-1. Use the local Dockerfile instead: `docker build -f Dockerfile.local -t shiftscheduler .`
-2. Build with network host mode: `docker build --network=host -t shiftscheduler .`
-3. Configure Docker to use system certificates if needed
\ No newline at end of file
+If you encounter errors like:
+```
+fatal: could not read Username for 'https://github.com': No such device or address
+```
+
+This is common in Docker build environments with:
+- Network restrictions
+- SSL certificate verification issues
+- Missing authentication credentials
+
+**Solutions:**
+1. **Use the main Dockerfile instead**: `docker build -t shiftscheduler .`
+2. **Use Docker Compose**: `docker-compose up --build`
+3. **Build with local files**: `docker build -f Dockerfile.local -t shiftscheduler .`
+
+### SSL Certificate Issues
+
+If you encounter SSL certificate errors:
+
+1. Use the local source approach: `docker build -t shiftscheduler .`
+2. Use Docker Compose: `docker-compose up --build`
+3. Build with network host mode: `docker build --network=host -t shiftscheduler .`
+
+### General Docker Issues
+
+- Ensure no other service is using port 5000
+- For development, use `docker build -f Dockerfile.local -t shiftscheduler .`
+- Check Docker daemon is running and accessible
